There was a beady eyed possum staring back at me!!! This was about 9am this morning and it looked very much at home. I thought is was a baby possum because it was fairly small...smaller than my chickens, but my husband thinks small full grown possum...maybe they are just smaller than I thought. Anyway, he "took care of it" and I want to know how dangerous this critter could be?? I have a coop with a screen room around it and bird netting on top. I close the screen room door everynight (but often after dark) but not the coop door figuring nothing that big can get in. The possum probably climbed down a tree, I've seen a couple of squirrels and birds get inside before, or...came in before I closed the screen room door and maybe couldn't get out??? My birds seem totally fine, oblivious. Should I set traps? Could they only harm baby chicks? Mine are 23 weeks old. We "free range" our 4 hens during the day, our yard is surrounded by 6 foot fencing. Possums and racoons are the only preditors that we have seen on the island. Thanks for your help.
